Gallery添加OnTouch事件问题
Gallery显示一个图片和两个按钮。
Gallery的adapter中，我每次只让他显示一张图片.
想通过判断滑动来切换图片。
dc_detail_gallery.setOnTouchListener(new View.OnTouchListener() { @Overridepublic boolean onTouch(View v, MotionEvent event) {// TODO Auto-generated method stub int action = event.getAction(); switch (action) { case MotionEvent.ACTION_DOWN: first_x = event.getX(); case MotionEvent.ACTION_MOVE: last_x = event.getX(); case MotionEvent.ACTION_UP: last_x = event.getX(); break; }if (index >= 0 && index <= images.length){ if(last_x < first_x) { if(index == images.length) dc_detail_gallery.setAdapter(new DcDetailGalleryAdapter(DcDetail.this, images, texts, prices,index)); else dc_detail_gallery.setAdapter(new DcDetailGalleryAdapter(DcDetail.this, images, texts, prices,++index));}if(last_x > first_x) { if(index > 0) dc_detail_gallery.setAdapter(new DcDetailGalleryAdapter(DcDetail.this, images, texts, prices,--index)); }} return true;}});
